Abstract
The utility model discloses a fuel gas pipeline connector, which comprises a body, and a connection pipe communicated with the body is installed on the body. Inner edges at two ends of the body are in inclined surface structures. A seal ring is arranged at a connection position of the body and an excircle of the connection pipe, and the seal ring is a wedge-shaped rubber seal ring. The wedge-shaped rubber seal ring is arranged in a containing cavity formed by the inclined surfaces at the ends of the body, fastening nuts and the connection pipe, and the connection pipe is ensured to slide relative to the body without leakage by screwing up the fastening nuts. A pullout-resistant ring is further arranged at the connection position of the body and the excircle of the connection pipe, and the pullout-resistant ring is a wedge-shaped nylon ring with an opening. The fastening nuts are screwed up to prevent the connection pipe from being pulled out from the body and leaking. The fuel gas pipeline connector is simple in structure, low in cost, good in sealing effect, high in safety factor and long in service life.
Description
Technical field
The utility model relates to a kind of pipe coupling, and is particularly related to a kind of gas pipeline joint of good sealing effect.
Background technique
As everyone knows, pipe coupling is a requisite link in the gas pipeline process of deployment, is used for two gas pipelines are connected and sealed; If because of the pipe coupling poor sealing; Cause combustion gas to reveal, possibly cause bigger security incident, therefore high to its sealing and reliability requirement; Traditional pipe coupling ubiquity complex structure, the shortcoming that sealing effect is bad and safety reliability is not high.
The model utility content
The purpose of the utility model is to provide a kind of gas pipeline joint, and it has simple in structure, good sealing effect and safe and reliable characteristics.
The purpose of the utility model is to realize through following technological scheme:
A kind of gas pipeline joint; It comprises body; The connecting tube that is connected with body is installed on the said body, and wherein, the connecting part of said body and connecting tube cylindrical is provided with seal ring; Said seal ring is pressed between connecting tube and the body through tightening nut, and the connecting part of said body and connecting tube cylindrical also is provided with the resistance to plucking circle.
The two ends inner edge of said body is a ramp structure, and said seal ring is the wedge-shaped rubber seal ring, and said wedge-shaped rubber seal ring places in the cavity volume that is formed by body end inclined-plane, nut and connecting tube.
The wedge shape nylon ring that said resistance to plucking circle is an opening closely is sheathed on the cylindrical of connecting tube.
The beneficial effect of the utility model does, said gas pipeline joint is not only simple in structure, and cost is lower; And good sealing effect, safety coefficient is high, long service life.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model gas pipeline joint.
Among the figure:
1, body; 2, tightening nut; 3, resistance to plucking circle; 4, wedge-type seal circle; 5, connecting tube.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the utility model gas pipeline joint, in present embodiment; A kind of gas pipeline joint; It comprises body 1, the connecting tube 5 that is connected with body 1 is installed on the said body 1, and the two ends inner edge of said body 1 is a ramp structure; Said body 1 is provided with wedge-type seal circle 4 with the connecting part of connecting tube 5 cylindricals; Said wedge-type seal circle 4 is processed for rubber material, and wedge-type seal circle 4 places in the cavity volume that is formed by body 1 end chamfer, tightening nut 2 and connecting tube 5, makes the inclined-plane of tightening nut 2 compress wedge shape seal ring 4 through tightening solid nut 2; Thereby the cylindrical that makes wedge-type seal circle 4 produce resiliently deformable extrusion body 1 inclined-plane and tightening nut 2 inclined-planes and connecting tube 5 reaches sealing purpose, and assurance connecting tube 5 slides with respect to body 1 and do not leak; And said body 1 also is provided with resistance to plucking circle 3 with the connecting part of connecting tube 5 cylindricals; Said resistance to plucking circle 3 is the wedge shape nylon ring of opening; Closely be sheathed on the cylindrical of connecting tube 5, the screwing force through tightening nut 2 prevents that connecting tube 5 from pulling out to form and leaks from body 1.
Said gas pipeline connector by using wedge-type seal circle 4 has guaranteed that connecting tube 5 slides with respect to body 1 and do not leak, and relies on the screwing force of tightening nut 2 to prevent that connecting tube 5 from pulling out to form simultaneously from body 1 and leaks, and not only simple in structure, cost is lower; And good sealing effect, safety coefficient is high, long service life.
